Knowledge of the effect accommodation on image quality peripheral retina is crucial for better understanding visual system, but only a few studies have been carried out in this area. This study was designed to evaluate higher order aberrations from third sixth Zernike polynomials central and up 23° off-axis. We used Hartmann–Shack aberrometer measure coefficients with both accommodated non-acco...

Title of Document: MAGNETOELASTIC COUPLING IN NiMnGa FERROMAGNETIC SHAPE MEMORY ALLOY Peng Zhao, Doctor of Philosophy, 2006 Directed By: Professor, Manfred Wuttig, Department of Materials Science and Engineering NiMnGa alloys have attracted extensive attention because their ferromagnetic characteristic provides an additional degree of freedom to control both the shape memory effect and the mult...

[1] Knowledge of the elastic properties and crystal chemistry of dense oxide structures plays an important role in interpreting the composition and mineralogy of planetary interiors. We report the effects of (Mg,Fe) substitution and nonstoichiometry due to Fe on the crystal structure, elastic constants (cij) and moduli (K0T, K0S, G0) of (Mg,Fe)O utilizing single-crystal X-ray diffraction and gi...

A novel experimental setup combining induction heating, contactless (infrared thermometer) temperature measurements, and custom 15 cm length SiC-tipped piezoelectric transducers has been developed to rapidly collect resonant ultrasound spectroscopy (RUS) data from metallic rectangular parallelepiped (RP) specimens heated in air. This is used over 70 of the lowest-frequency resonance modes a sin...

Purpose: For years, concern has persisted that hydroquinone exposure in humans may be associated with increased risk of cancer but proving this been elusive. The purpose study is to use the TriNetX database quantify humans. Methods: We used platform create 2 cohorts patients, both without any prior diagnosis skin cancer. One cohort had received which was determined by medication code 5509 syste...

We investigate the formation mechanisms of covalently bound C4H4+ cations from direct ionization hydrogen bonded dimers acetylene molecules through fragment ion and electron coincident momentum spectroscopy quantum chemistry calculations. The measurements momenta energies two outgoing electrons one in triple-coincidence allow us to assign channels associated with different ionic fragments. meas...

Studying the physical properties of materials under high pressure and temperature through experiments is difficult. Theoretical simulations can compensate for this deficiency. Currently, large-scale using machine learning force fields are gaining popularity. As an important nuclear energy material, evolution uranium extreme conditions still unclear. Herein, we trained accurate field on α-U pred...

Se sintetizaron nanovarillas de óxido manganeso en fase cristalina beta (β-MnO2). Microscopía electrónica barrido (SEM) y difracción rayos-X (XRD) confirmaron la morfología cristalina, respectivamente. Mediante teoría del funcional densidad (DFT), se calcularon las propiedades mecánicas teóricas β-MnO2 con el programa CASTEP. realizó una optimización geometría celda unitaria, determinándose con...
